A Centers for Disease Control and Prevention (CDC) advisory panel on Monday indicated it could take a substantially different approach to booster doses of COVID-19 vaccines than the one proposed by the Biden administration.
Members of the CDC’s Advisory Committee on Immunization Practices (ACIP) said the evidence on boosters is not clear and indicated it would likely consider a risk-based approach that would prioritize residents of long-term care facilities and health workers rather than all eligible Americans at once.
COVID-19 vaccines continue to maintain high protection against severe disease, hospitalization and death. While some studies have found some waning of effectiveness against infection, members of the panel said the evidence is not clear enough to justify a booster recommendation.
Vaccine efficacy has ranged between 39 percent and 84 percent, according to several studies.
